27 This module implements a client interface to the POP3 protocol,
28 enabling a perl5 application to talk to POP3 servers. This documenta‐
29 tion assumes that you are familiar with the POP3 protocol described in
30 RFC1939.
31 A new Net::POP3 object must be created with the new method. Once this
33 has been done, all POP3 commands are accessed via method calls on the
34 object.
35
37 new ( [ HOST ] [, OPTIONS ] 0
38 This is the constructor for a new Net::POP3 object. "HOST" is the
39 name of the remote host to which an POP3 connection is required.
40 "HOST" is optional. If "HOST" is not given then it may instead be
42 passed as the "Host" option described below. If neither is given
43 then the "POP3_Hosts" specified in "Net::Config" will be used.
44 "OPTIONS" are passed in a hash like fashion, using key and value
46 pairs. Possible options are:
47 Host - POP3 host to connect to. It may be a single scalar, as
49 defined for the "PeerAddr" option in IO::Socket::INET, or a refer‐
50 ence to an array with hosts to try in turn. The "host" method will
51 return the value which was used to connect to the host.
52 ResvPort - If given then the socket for the "Net::POP3" object will
54 be bound to the local port given using "bind" when the socket is
55 created.
56 Timeout - Maximum time, in seconds, to wait for a response from the
58 POP3 server (default: 120)
59 Debug - Enable debugging information
61
63 Unless otherwise stated all methods return either a true or false
64 value, with true meaning that the operation was a success. When a
65 method states that it returns a value, failure will be returned as
66 undef or an empty list.
67 auth ( USERNAME, PASSWORD )
69 Attempt SASL authentication.
70 user ( USER )
72 Send the USER command.
73 pass ( PASS )
75 Send the PASS command. Returns the number of messages in the mail‐
76 box.
77 login ( [ USER [, PASS ]] )
79 Send both the USER and PASS commands. If "PASS" is not given the
80 "Net::POP3" uses "Net::Netrc" to lookup the password using the host
81 and username. If the username is not specified then the current
82 user name will be used.
83 Returns the number of messages in the mailbox. However if there are
85 no messages on the server the string "0E0" will be returned. This
86 is will give a true value in a boolean context, but zero in a
87 numeric context.
88 If there was an error authenticating the user then undef will be
90 returned.
91 apop ( [ USER [, PASS ]] )
93 Authenticate with the server identifying as "USER" with password
94 "PASS". Similar to "login", but the password is not sent in clear
95 text.
96 To use this method you must have the Digest::MD5 or the MD5 module
98 installed, otherwise this method will return undef.
99 banner ()
101 Return the sever's connection banner
102 capa ()
104 Return a reference to a hash of the capabilties of the server.
105 APOP is added as a pseudo capability. Note that I've been unable
106 to find a list of the standard capability values, and some appear
107 to be multi-word and some are not. We make an attempt at intelli‐
108 gently parsing them, but it may not be correct.
109 capabilities ()
111 Just like capa, but only uses a cache from the last time we asked
112 the server, so as to avoid asking more than once.
113 top ( MSGNUM [, NUMLINES ] )
115 Get the header and the first "NUMLINES" of the body for the message
116 "MSGNUM". Returns a reference to an array which contains the lines
117 of text read from the server.
118 list ( [ MSGNUM ] )
120 If called with an argument the "list" returns the size of the mes‐
121 sage in octets.
122 If called without arguments a reference to a hash is returned. The
124 keys will be the "MSGNUM"'s of all undeleted messages and the val‐
125 ues will be their size in octets.
126 get ( MSGNUM [, FH ] )
128 Get the message "MSGNUM" from the remote mailbox. If "FH" is not
129 given then get returns a reference to an array which contains the
130 lines of text read from the server. If "FH" is given then the lines
131 returned from the server are printed to the filehandle "FH".
132 getfh ( MSGNUM )
134 As per get(), but returns a tied filehandle. Reading from this
135 filehandle returns the requested message. The filehandle will
136 return EOF at the end of the message and should not be reused.
137 last ()
139 Returns the highest "MSGNUM" of all the messages accessed.
140 popstat ()
142 Returns a list of two elements. These are the number of undeleted
143 elements and the size of the mbox in octets.
144 ping ( USER )
146 Returns a list of two elements. These are the number of new mes‐
147 sages and the total number of messages for "USER".
148 uidl ( [ MSGNUM ] )
150 Returns a unique identifier for "MSGNUM" if given. If "MSGNUM" is
151 not given "uidl" returns a reference to a hash where the keys are
152 the message numbers and the values are the unique identifiers.
153 delete ( MSGNUM )
155 Mark message "MSGNUM" to be deleted from the remote mailbox. All
156 messages that are marked to be deleted will be removed from the
157 remote mailbox when the server connection closed.
158 reset ()
160 Reset the status of the remote POP3 server. This includes reseting
161 the status of all messages to not be deleted.
162 quit ()
164 Quit and close the connection to the remote POP3 server. Any mes‐
165 sages marked as deleted will be deleted from the remote mailbox.
166
168 If a "Net::POP3" object goes out of scope before "quit" method is
169 called then the "reset" method will called before the connection is
170 closed. This means that any messages marked to be deleted will not be.
